WordPress spam – WordPress bloggers’ nightmare is far from becoming history but Hashcash almost promises zero tolerance.
Hashcash.io is introducing a method that forces the user’s browser to solve math. This method is said to secure sites against brute force attacks. It leverages open technology including Asm.js, HTML5 and Web Workers to force your login and comment forms disabled until your browsers has solved the required math. I think this is a new way to keep bot and spammers panting off your blog.
